Abstract

L'invention concerne un appareil de stockage sécurisé, de même que des procédés de stockage et de lecture de données dans un réseau de stockage sécurisé. L’appareil de stockage sécurisé est configuré pour présenter à un client un disque virtuel, le disque virtuel étant cartographié en fonction de la pluralité de dispositifs de stockage physiques. L’appareil de stockage sécurisé est capable d'exécuter des instructions de programme configurées pour générer une pluralité de blocs de données secondaires en réalisant des opérations de séparation et de cryptage sur un bloc de données primaires reçu du client pour stockage sur le disque virtuel et reconstituer le bloc de données primaires à partir d’au moins une partie de la pluralité de blocs de données secondaires stockés en portions sur des dispositifs de stockage physiques correspondants en réponse à une demande du client. On utilise des compteurs d’écriture rédigés avec les blocs de données secondaires pour déterminer si les blocs de données secondaires ont été stockés correctement.
